Y '0 aZZ whom may concern:

Be itknown that I, Lnsnrn R. KI HL, a citizen of the United States, residing at Baton, in the county of Colfax and. Fatate of New Mexico, havexinvented new and useful IHIPYOVQDZGHtS in Locomotive-Flange )ilers, of which the following is a specification. 7

This invention relates to lubricating devices, and: has for its object the provision of a: novel pressure operated device for supplying oil-to the flanges of the drivers of a locomotive. A p

The essentialfeatu-re is the provision of a device of this character which is connected with the exhaust steam line whereby the proper pressure will be'developedtor' torcing oil froma reservoir and supplying it to the wheel flanges.

7 Another object is the provision etad evice for this purpose: in Whichthe properpres: sure will be automatically inaintaineth means being", however, provided whereby the pressure may be varied.

Yet another object is the provision of a peculiar arrangement designed to prevent damage by freezing of the water of condensation; Q p

lVith, the; above and other objects and advantages in view, the i invention consists in the details of construction and arrangement of parts to'be. hereinafter fully described and-claimed, and illustrated in the accoinpa-nving drawings, in which z Figure 1 is a somewhatdiagrannnaticside equipped with my elevation of a: locomotive device 1 v wFigure- 2 is a view on the line 2-2 t Figure 1 looking downwardlyl v Figure 3 is avertical section through the device. r- I cFigure 4 is a; section on the line i -4t of li i'gurej Figure Figure I t Figure 6 is a'deta-il: section through the pressure'control valve:

v Referring more particularly to the drawings; the, letter A designates a, locomotive having the driver Wheels B which areto be lubricated; Inca-rryingout iny inventionl provideanautomatic oiling device which in cludes" a' casing 10' constituting areservoir tor-oila-nd uponwhich is mounted a: second casing 11 which constitutes" nixingchain.-

isa section on'thel line 55 of are here represented as detachable and con- 'nect'edby threadedfianges l2 and 1 3 but may be cast in suitable form if preferred. The casing is arovided with a drain-valve 14c and filling plug 15, while the casing 11 has asuitable cap 16. I l Vithin the casing 10 is a pipe coil 1'? having several c-onvolutions andhaving one end 1 8 term nating" somewhat 7 above center of tne casing 10. Connected with or formed integrally upon the other end of this coil is a tube 19 which extends through a hole 20 n the bottom of the casing 11 and which is surrounded by an upstanding pipe 21 defining a chamber or air" space about the tube 19 for permitting expansion without damage, in case the contents of the casino- 10 freeze; The'top of the pipe 21 is closed except for a sinall hole within which the upper end of the tube 19 is secured The device is used. in connection withthe exhaust line 23 of the lccoinotiveandl have shown the casing 11 as provided with inlet and outlet pipes Qetand :25, respe'ctivelv, the latter of which i has connected therewith branches 26which lead to the flange of the wheels B for supplying them with. oil. I The inner end o'fjthe pipe 2% is inclined or otherw se formed to; define aseatlifor a flap or other" suitable valve 28 carried an arm QQpivoted at. 30 at, the top of the casing ll).

The top of the casing 10 is: formed with a hole 3ladapted to be closed by a valve 32 which has its stern 33 enga ed by the arm 2d so that the position of the arm; 29 will govern thedegr'ee of opening of the valve For adjusting the throivof the lever 29, l jprovi dean elongated screw threaded through a. boss on thetop of thecasing 11. The upper endo'fthis screw carries a head 36 while its-lower end isso positioned as to be engaged by the lever 29 for limiting opening movement of the valve 28 and there'- by; controlling; the entrance of steam to the i gll- 4 a a Interposethin the; pipe Qtis; at ca-sing3'i within which is mounted-a valve 38 having a conical top-39 adapted to, engage a seat it); The; v i e is formedwitlrp'assages all for perinitt .g aliinited pressure of steam to pass therethrough. V

In the operation, steainjpas ses through thepipe 24; around the valve-38 and passes into the/casing- 11. Th9iIllUSlllllgfStEEUH iniplnging aga nst the valve 28; lifts it an d the leverfll}, and also liftsthe valveBQ; from its seat; TheFcasingt-ll. is; then of course full ill of steam and a certain amount passes out through the outlet pipe Owing to the :lact that the upper end of the pipe 19 is in con'imunication with the interior of the casing 11 and owing to the fact that the valve 32 is unseated, leaving the opening 31 open to a great or less extent, it will be clear that while there is a pressure exerted through the pipe 19 and also upon the oil contained within the casing 10, these pressures will balance or equalize. After the steam has been passing into and through the casing 11 for a short period of time, the pipe coils 17 will become tilled with water of condensation. It is of course understood that initially the casing is tilled with oil and it will be quite obvious that as water of condensation acciunulates within the coils 17 and passes out through the discharge end 18 thereof the level of the oil will he raised and a quantity thereof will pass out through the opening 81 and be mixed with the stean'i in the casing 11 and discharged therewith through the pipe and pipes 26 to the flanges oi the wheels to be oiled. \Vhen the device is first set in operation it is quite clear that some short time will be necessary in order to permit the water of condensation to accumulate within the coils 17 to a sullicient extent to raise the oil level and etl'ect discharge of the oil to the wheel flanges. However, after the initial starting it is quite evident that even the accumulation of one or two drops or any other small quantity of water of condensation will raise the oil level within the casing 10 to a corresponding degree and the outlet of oil will be consequently automatic in accordance with this action.

After the device has been in use for sometime the amount of oil remaining within the casing 10 and floating upon the body or water of condensation accumulated therein will be continually decreased. In order that the oil supply may then be replenished the valve l-l opened to permit draining of the water and the filling plug 15 is removed so that additional oil may be poured into the casing 10 to bring the supply up to normalv W'hcn draining oi the water is cll'ected it will be seen that it is impossible to drain the coils 1.7 and it is intended that these coils be leitt substantially lull oi. the water of condensation to avoid delay in the operation when subsequent use is desired. The rate o'l flow oi oil is oi": course governed by the posititm ol the arm 29 controlling the valve 32 and the position of this arm is in turn contrijilled by the adjustment of the screw 3st which limits the movement of the arm and the degree of opening of the valve 28 controlling the pressure of steam.

Even in s vere weather it is apparent that there is little danger of freezing of any of the essential parts inasmuch as the coils 17 are enclosed within the body of oil in the casing 10 and as the pipe 15) enclosed within an air chamber. However, if the contents of the casing 10 should freeze, and consequently expand this expansion is taken care of as the air within the chamber 22 may compress and consequently permit e2;- pansion without breakage of any of the parts.

ll the steam pressure should become excessive, the valve 38 will engage against its seat -l0, cutting off oonn'nmncation through the pipe 24: except that the passage" it will still permit a limited amount oi steam to pass.

From the foregoing description and a study of the drawings it will be apparel'it that I have thus provided a very simple automatic device tor the purpose specified which will operate on the hydrostatic principle and controlled by an easily regulable steam aressure. Ample provision has been made tor effecting all necessary adjustment and the parts are all so constructed and correlated as to insure positive and ellicient action.

-While I have shown and described the preferred embodiment ol? the invention, it should be understood that I reserve the right to make such changes in the term, construction and arrangement of parts as will not depart from the spirit oil the i11- vention or the scope of the sub-joined claims.
